3. DESCRIPTION OF OPERATIONS

3.1 DRIVE SYSTEM

Fig.3-1

3.1.1 OutlineOriginals are transported by the original feed motor, read motor and original exit/reverse motor. Each motor has a drive section for the following operations:

Original feed motor drive section: picks up originals and drives the registration roller.Read motor drive section: transports originals and drives parts such as the pre-reading

roller.Original exit/reverse motor drive section: exits and reverses originals, and drives the exit/reverse roller.

The Original feed motor rotates reversely when the originals are being transported at the registration roller, compared to its rotational direction when they are being picked up. The original exit/reverse motor also rotates reversely when the originals are being reversed and trans-ported, compared to its rotational direction when they are being exited.The read motor always rotates in a constant direction.

3.1.2 Original feed motor drive section

Fig.3-2

When an original is placed on the original tray and the RADF receives a feed request signal from the equipment, the feeding of the original is started.The original empty sensor detects the presence of the original, and then the pickup roller is lowered by the drive from the original pickup solenoid.The Original feed motor rotates, and the pickup roller and the feed roller then rotate in a normal direc-tion (shown in a solid line in the figure) to guide the original into the transport path. Then the original is transported to the registration roller to be aligned.The original aligned with the registration roller is then transported by the reverse rotation of the Original feed motor (shown in a dotted line in the figure).A one-way clutch is installed inside of each gear of the feed roller and the registration roller, so these gears will not be driven in a reverse rotation. When the original empty sensor detects that there is no original on the original tray, the original pickup solenoid is turned OFF and the pickup roller is raised. The original pickup solenoid is the one can operate both suction and recovery.

When the data of the original have been scanned, the original is exited to the original exit tray by the exit/reverse roller driven by the exit motor (shown in a solid line in the figure).In the duplex scanning mode, the gate solenoid is turned ON and the reverse flapper is lowered to switch the transport path to the reverse tray side when the scanning of one side of the original is com-pleted.When the reverse flapper is lowered, the original is temporarily transported to the reverse tray, and then the exit motor rotates reversely to return the original to the transport path switched for reverse operation (shown in a dotted line in the figure).The reversed original is aligned with the reverse registration roller, and then the other side of the origi-nal is scanned. When the scanning is completed, the original is exited to the original exit tray.

3.2 Original Size DetectionThe original tray width sensor, original length detection sensor, and original width detection sensors-1 and -2 work in combination to detect the size of originals.

Fig.3-5

3.2.1 OutlineWhen an original is placed on the original tray, the width of the original is detected by the positions of the original width guides. Then the original width sensors -1 and -2 and the original length detection sensor detect the size of the original being transported. Based on the detection result of these sensors, the size of the original is finally determined.

3.2.2 Original tray width sensorThe original tray width sensor detects the width of an original placed on the original tray.It is detected by the brush attached to the rack moving on the original tray width sensor, which is a board with the different length of the patterns written.This brush is moved as the original width guide is moved. Signals (TWID0S, TWID1S, TWID2S) are opened and shorted to SG by this movement.The combination of these short (= low level) and open (= high level) can determine the width of the orig-inal.Sizes detectable in combination of these open and short of the signals are as follows:

3.4 DESCRIPTION OF CIRCUIT

3.4.1 Drive Circuit for Feed Motor

Fig.3-6

This circuit controls the rotation/stoppage and the direction of rotation, excitation mode and motor cur-rent of the feed motor.A drive clock signal (FMOT-CLK) and rotation direction signal (FMOT-CW/CCW) are input to control the speed and direction of the motor rotation.When the level of the enabling signal (FMOT-Enable) is set to "L", motor current is turned OFF regard-less of the state of other signals.For the excitation mode, either of 2 phase excitation, 1-2 phase excitation, W1-2 phase excitation, 2W1-2 phase excitation or the 4W1-2 phase excitation can be selected using the excitation switching signal (FMOT-Mode1/FMOT-Mode2).The edge switching signal (FMOT-Mode3) is used to specify the switching timing for excitation phase either from when both the rise and decay edge of the CLK input are detected or when only the rising edge is detected.Motor current value can be set discretionary by changing the level of the reference setting signal (FMOT-REF).

3.4.2 Drive Circuit for Read Motor

Fig.3-7

This circuit controls the rotation/stoppage and the direction of rotation, excitation mode and motor cur-rent of the read motor.A drive clock signal (RMOT-CLK) and rotation direction signal (RMOT-CW/CCW) are input to control the speed and direction of the motor rotation.When the level of the enabling signal (RMOT-Enable) is set to "L", motor current is turned to OFF regardless of the state of other signals.For the excitation mode, either of 2 phase excitation, 1-2 phase excitation, W1-2 phase excitation, 2W1-2 phase excitation or the 4W1-2 phase excitation can be selected using the excitation switching signal (RMOT-Mode1/RMOT-Mode2).The edge switching signal (RMOT-Mode3) is used to specify the switching timing for excitation phase either from when both the rise and decay edge of the CLK input are detected or when only the rising edge is detected.Motor current value can be set discretionary by changing the level of the reference setting signal (RMOT-REF).

3.4.3 Drive Circuit for Exit Motor

Fig.3-8

This circuit controls the rotation/stoppage and the direction of rotation, excitation mode and motor cur-rent of the exit motor.A drive clock signal (EMOT-CLK) and rotation direction signal (EMOT-CW/CCW) are input to control the speed and direction of the motor rotation.When the level of the enabling signal (EMOT-Enable) is set to "L", motor current is turned OFF regard-less of the state of other signals.As IC3-10pin (MODE1) is connected to +5V, excitation mode is applied at 1-2 phase excitation.The edge switching signal (EMOT-Mode3) is used to specify the switching timing for excitation phase either from when both the rise and decay edge of the CLK input are detected or when only the rising edge is detected.Motor current value can be set discretionary by switching the level of the reference switching signal (EMOT-REFS0,EMOT-REFS1).

3.4.4 Reset Circuit

Fig.3-9

This circuit generates a reset signal when the power is turned ON and the power voltage is blocked or cut off/lowered temporarily.At the power-ON, the circuit shifts the level of the reset signal from L to H to put the CPU in a opera-tive state after the reset pulse duration (Tpd) determined by the capacitance of C58 has passed from when the power voltage has reached the supervisory voltage (Vs) divided by R116 and R117.When a power voltage drop (cutoff, temporary cutoff, temporary low voltage) occurs and the power volt-age becomes lower than the set value for the supervisory voltage for the power, the circuit sets the level of the reset signal (RESET) to L to put the CPU in a halt state.

MR-3019 MAINTENANCE AND REWRITING ROM April 2006 TOSHIBA TEC

7 - 2

7.2 Rewriting ROM (Firmware Updating)It is feasible to update the firmware automatically by connecting the download jig to the PC board and turning the power of the equipment ON. The download jig K-PWA-DLM-320 is used.

< Procedure >

(1) Turning OFF the power of the equipment and take off the RADF rear cover.(2) Connect the download jig with the connector (CN81) on the PC board.(3) While pressing [0] and [8] simultaneously, turn ON the power. (rewriting data starts)(4) During the data is rewritten, the LED on the download jig lights. When the data rewriting is com-

pleted, the LED blinks slowly (at an interval of 0.8 sec.). If the LED blinks fast (at an interval of 0.1 sec.), the rewriting has been failed.

(5) Turn OFF the power of the equipment and remove the download jig.(6) Install the RADF rear cover.

* If rewriting data is failed, turn OFF the power and repeat the procedure.
